The present disclosure provides compounds that are tyrosine kinaseinhibitors, in particular BLK, BMX, EGFR, HER2, HER4, ITK, TEC, BTK, andTXK and are therefore useful for the treatment of diseases treatable byinhibition of tyrosine kinases such as cancer and inflammatory diseasessuch as arthritis, and the like. Also provided are pharmaceuticalcompositions containing such compounds and processes for preparing suchcompounds.

The human genome contains at least 500 genes encoding protein kinases.Many of these kinases have been implicated in human disease and as suchrepresent potentially attractive therapeutic targets. For example EGFRis overexpressed in breast, head and neck cancers and the overexpressionis correlated with poor survival (see Do N. Y., et al., Expression ofc-ErbB receptors, MMPs and VEGF in squamous cell carcinoma of the headand neck. Oncol Rep. August 12:229-37. 2004 and Foley J., et al., EGFRsignaling in breast cancer: had to the bone. Semin Cell Dev Biol.21:951-60. 2010). HER2, another EGFR family member, also is amplified oroverexpressed in up to 30% of breast cancers, also correlating with poorsurvival (see Murphy C. G, Modi S. HER2 breast cancer therapies: areview. Biologics 3:289-301. 2009). HER4, also in the EGFR family, isoverexpressed in head and neck squamous cell carcinomas (see Rosen F.S., et al. The primary immunodeficiencies. New Engl. J. Med. 333:431-40,1995). Other studies show decreased expression of HER4 in certaincancers and suggest tumor suppressor activity (see Thomasson M. et al.,ErbB4 is downregulated in renal cell carcinoma—a quantitative RT-PCR andimmunohistochemical analysis of the epidermal growth factor receptorfamily. Acta Oncol. 43:453-9. 2004). Overall the data support a role formembers of the EGFR family in cancer. ITK, a member of the TEC kinasefamily, is involved in activation of T cells and mast cells (see Iyer A.S. et al., Absence of Tee Family Kinases Interleukin-2 Inducible T cellKinase (Itk) and Bruton's Tyrosine Kinase (Btk) Severely Impairs Fc{epsilon}RI-dependent Mast Cell Responses. J. Biol Chem.; 286:9503-13.2011) and is a potential target in inflammatory immune diseases such asasthma. Mice deficient in ITK are resistant to development of allergicasthma (see Sahu N, et al., Differential sensitivity to Itk kinasesignals for T helper 2 cytokine production and chemokine-mediatedmigration. J. Immunol. 180:3833-8. 2008). Another family member, BMX, isinvolved in supporting tumor angiogenesis through it's role in the tumorvascular endothelium (see Tu T, et al., Bone marrow X kinase-mediatedsignal transduction in irradiated vascular endothelium. Cancer Res.68:2861-9. 2008) and is also progressively up-regulated during bladdercancer progression (see Guo S., et al., Tyrosine Kinase ETK/BMX IsUp-Regulated in Bladder Cancer and Predicts Poor Prognosis in Patientswith Cystectomy. PLoS One. 6:e17778. 2011) suggesting a potentialtherapeutic target in this type cancer. The B lymphoid kinase (BLK) islinked through genetic association with a variety of rheumatic diseasesincluding systemic lupus erythematosus and systemic sclerosis (see ItoI, et al., Association of the FAm167A-BLK region with systemicsclerosis. Arthritis Rheum, 62:890-5. 2010).

Bruton's tyrosine kinase (abbreviated as BTB), a member of the Tecfamily non-receptor tyrosine kinases that is essential for B cellsignaling downstream from the B-cell receptor. It is expressed in Bcells and other hematopoietic cells such as monocytes, macrophages andmast cells. It functions in various aspects of B cell function thatmaintain the B cell repertoire (see Gauld S. B. et al., B cell antigenreceptor signaling: roles in cell development and disease. Science,296:1641-2. 2002.)). Clinical validation of the role of B cells in RAhas been provided by the efficacy of Rituxan (an anti-CD20 antibody),which depletes B cells as a mechanism of action (see Perosa F., et al.,CD20-depleting therapy in autoimmune diseases: from basic research tothe clinic. J Intern Med. 267:260-77. 2010 and Dörner T, et al.Targeting B cells in immune-mediated inflammatory disease: acomprehensive review of mechanisms of action and identification ofbiomarkers. Pharmacol Ther. 125:464-75. 2010.). Btk is known to berequired for B cell development because patients with the diseaseX-linked agammaglobulinemia (see Rosen F. S., et al., The primaryimmunodeficiencies. N Engl J Med. 333:431-40. 1995). Notably,small-molecule BTK inhibitors in pre-clinical development have beenshown to be efficacious in collagen-induced arthritis (see Pan Z., etal., Discovery of selective irreversible inhibitors for Bruton'styrosine kinase. J. Med. Chem. 2:58-61. 2007). However, the potentialadvantage of a BTK inhibitor (beyond the inherent advantage of asmall-molecule over a biologic) is that modulation of BTK can inhibit Bcell function without permanent removal of the B cell itself. Therefore,the long periods of low B cell levels experienced with Rituxan should beavoidable by targeting BTK.

In addition, the disease modifying activities of BTK are expected toextend beyond those of Rituxan because of effects on addition cellulartargets that are involved in propagation of disease. For instance,antigen induced mast cell degranulation is impaired in mast cellsderived from the bone marrow of BTK deficient mice, demonstrating thatBTK is downstream of the FcεR1 receptor (see Setoguchi R., et al.,Defective degranulation and calcium mobilization of bone-marrow derivedmast cells from Xid and BTK-deficient mice. Immunol Lett. 64:109-18.1998). A similar signaling module exists in monocytes and macrophagesfor the FcγR1 receptor indicating BTK inhibition is highly likely tomodulate TNF production in response to IgG. Both mast cells andmacrophages are thought to contribute to propagation of the inflammatorycytokine environment of the diseased synovium.

In addition to the peripheral and synovial effects of BTK inhibitiondescribed above, there is evidence that BTK inhibition will have boneprotective effects in the inflamed joint (see Gravallese E. M., et al.,Synovial tissue in rheumatoid arthritis is a source of osteoclastdifferentiation factor. Arthritis Rheum. 43:250-8. 2000). Studies withmice that are either deficient in BTK or have impaired BTK function havedemonstrated that Rank ligand-induced osteoclast differentiation isimpaired in the absence of BTK function (see Lee S. H., et. al., The tecfamily tyrosine kinase BTK Regulates RANKL-induced osteoclastmaturation. J. Biol. Chem. 283:11526-34. 2008). Taken together thesestudies suggest a BTK inhibitor could inhibit or reverse the bonedestruction that occurs in RA patients. Given the importance of B cellsautoimmune disease. BTK inhibitors could also have utility in otherautoimmune diseases such as systemic lupus erythematosus (see ShlomchikM. J., et. al., The role of B cells in lpr/lpr-induced autoimmunity. J.Exp Med. 180:1295-1306. 1994). Notably, an irreversible BTK inhibitorhas been shown to display efficacy in the mouse MRL/lpr lupus model,reducing autoantibody production and renal damage (see Honigberg L. A.,The Bruton tyrosine kinase inhibitor PCI-32765 blocks B-cell activationand is efficacious in models of autoimmune disease and B-cellmalignancy. Proc. Natl. Acad. Sci. 107:13075-80. 2010).

There is also potential for BTK inhibitors for treating allergicdiseases see Honigberg, L., et. al., The selective BTK inhibitorPCI-32765 blocks B cell and mast cell activation and prevents mousecollagen indiced arthritis. Clin. Immunol. 127 S1:S111. 2008). Inaddition, the irreversible inhibitor suppresses passive cutaneousanaphylaxis (PCA) induced by IgE antigen complex in mice (see Honigberg,L., et. al., The selective BTK inhibitor PCI-32765 blocks B cell andmast cell activation and prevents mouse collagen indiced arthritis.Clin. Immunol, 127 S1:S111. 2008). These findings are in agreement withthose noted with BTK-mutant mast cells and knockout mice and suggestthat BTK inhibitors may be useful for the treatment of asthma, anIgE-dependent allergic disease of the airway.

In addition, platelet aggregation in response to collagen orcollagen-related peptide is impaired in XLA patients who lack BTKfunction (see Quek L. S, et al., A role for Bruton's tyrosine kinase(BTK) in platelet activation by collagen. Curr. Biol. 8:1137-40.1998).This is manifested by changes downstream from GPIV, such asphosphorylation of PLCgamma2 and calcium flux, which suggests potentialutility in treating thromboembolic diseases.

Preclinical studies with a selective inhibitor of BTK have shown effectson spontaneous canine B cell lymphomas suggesting a potential utility inhuman lymphomas or other hematologic malignancies including chroniclymphocytic leukemia.

Accordingly, there is a need for compounds that inhibit tyrosine kinasesthereby providing treatment for diseases such as autoimmune diseases,thromboembolic diseases and cancer. The present disclosure can fulfillthis need and related needs.

The term “electron withdrawing group” refers to a chemical substituentthat modifies the electrostatic forces acting on a nearby chemicalreaction center by withdrawing negative charge from that chemicalreaction center. Thus, electron withdrawing groups draw electrons awayfrom a reaction center. As a result, the reaction center is fractionallymore positive than it would be in the absence of theelectron-withdrawing group. In some embodiments, the chemical reactioncenter is one of the two carbons forming the carbon-carbon double bond(olefin). In some embodiments, the chemical reaction center is theolefin carbon attached to EWG. The electron withdrawing group functionsto draw charge or electrons away from this olefin carbon thereby makingthe olefin carbon electron deficient (relative to the absence of theelectron withdrawing group). The electron deficient olefin carbon isthereby rendered more reactive toward electron rich chemical groups,such as the sulfhydryl of a kinase active site cysteine.

The compounds of the present disclosure may have asymmetric centers.Compounds of the present disclosure containing an asymmetricallysubstituted atom may be isolated in optically active or racemic forms.It is well known in the art how to prepare optically active forms, suchas by resolution of materials. All chiral, diastereomeric, racemic formsare within the scope of this disclosure, unless the specificstereochemistry or isomeric form is specifically indicated.

Certain compounds of Formula (IA), (I′) or (I) (or any of theembodiments thereof described herein), can exist as tautomers and/orgeometric isomers. All possible tautomers and cis and trans isomers, asindividual forms and mixtures thereof are within the scope of thisdisclosure. Additionally, as used herein the term alkyl includes all thepossible isomeric forms of said alkyl group albeit only a few examplesare set forth. Furthermore, when the cyclic groups such as aryl,heteroaryl, heterocyclyl are substituted, they include all thepositional isomers albeit only a few examples are set forth.Furthermore, all polymorphic forms and hydrates of a compound of Formula(IA), (I′) or (I) (or any of the embodiments thereof described herein),are within the scope of this disclosure.

“Oxo” or “carbonyl” means C═(O) group.

“Optional” or “optionally” means that the subsequently described eventor circumstance may but need not occur, and that the descriptionincludes instances where the event or circumstance occurs and instancesin which it does not. For example, “heterocyclyl group optionallysubstituted with an alkyl group” means that the alkyl may but need notbe present, and the description includes situations where theheterocyclyl group is substituted with an alkyl group and situationswhere the heterocyclyl group is not substituted with alkyl.

A “pharmaceutically acceptable carrier or excipient” means a carrier oran excipient that is useful in preparing a pharmaceutical compositionthat is generally safe, non-toxic and neither biologically nor otherwiseundesirable, and includes a carrier or an excipient that is acceptablefor veterinary use as well as human pharmaceutical use. “Apharmaceutically acceptable carrier/excipient” as used in thespecification and claims includes both one and more than one suchexcipient.

“Substituted alkyl” means alkyl group as defined herein which issubstituted with one, two, or three substituents independently selectedfrom hydroxyl, alkoxy, carboxy, cyano, carboxy, alkoxycarbonyl,alkylthio, alkylsulfonyl, halo, —CONRR′ or NRR′ (where each R ishydrogen, alkyl, cycloalkyl, hydroxyalkyl, or alkoxyalkyl, and each R′is hydrogen, alkyl, or cycloalkyl) or heterocyclyl (preferablyheterocycloamino) which is optionally substituted with one or two groupsindependently selected from alkyl, hydroxyl, alkoxy, alkylthio,alkylsulfonyl, halo, or —CONRR′ where R and R′ are as defined above.

“Treating” or “treatment” of a disease includes:

(1) preventing the disease, i.e. causing the clinical symptoms of thedisease not to develop in a mammal that may be exposed to or predisposedto the disease but does not yet experience or display symptoms of thedisease;

(2) inhibiting the disease, i.e., arresting or reducing the developmentof the disease or its clinical symptoms; or

(3) relieving the disease, i.e., causing regression of the disease orits clinical symptoms.

A “therapeutically effective amount” means the amount of a compound ofFormula (IA), (I′) or (I) (or any of the embodiments thereof describedherein), that, when administered to a mammal for treating a disease, issufficient to effect such treatment for the disease. The“therapeutically effective amount” will vary depending on the compound,the disease and its severity and the age, weight, etc., of the mammal tobe treated.

Compositions can take the form of tablets, pills,capsules, semisolids, powders, sustained release formulations,solutions, suspensions, elixirs, aerosols, or any other appropriatecompositions.

The choice of formulation depends on various factors such as the mode ofdrug administration (e.g., for oral administration, formulations in theform of tablets, pills or capsules are preferred) and thebioavailability of the drug substance. Recently, pharmaceuticalformulations have been developed especially for drugs that show poorbioavailability based upon the principle that bioavailability can beincreased by increasing the surface area i.e., decreasing particle size.For example, U.S. Pat. No. 4,107,288 describes a pharmaceuticalformulation having particles in the size range from 10 to 1,000 nm inwhich the active material is supported on a crosslinked matrix ofmacromolecules. U.S. Pat. No. 5,145,684 describes the production of apharmaceutical formulation in which the drug substance is pulverized tonanoparticles (average particle size of 400 nm) in the presence of asurface modifier and then dispersed in a liquid medium to give apharmaceutical formulation that exhibits remarkably highbioavailability.

The compositions are comprised of in general, a compound of formula(IA), (I′) or (I) in combination with at least one pharmaceuticallyacceptable excipient.

Biological Examples Tyrosine Kinase TR-FRET Assay

Inhibition of tyrosine kinase enzymatic activity by compounds ismeasured using time-resolved fluorescence resonance energy transfer(TR-FRET) (Invitrogen pamphlet:

Optimization of a LanthaScreen Kinase assay for BTK). Here, a signal isobserved only when a Europium-coupled phophotyrosine antibody binds thephosphorylated peptide. Compounds are first prepared in 100% DMSO andserially diluted 10 times via 3-fold dilution. 2.5 μl of inhibitor at4-fold the final assay concentration is next transferred to the 384-wellassay plate (Corning Catalog #3676). A solution of 2-fold the finalconcentration of appropriate kinase enzyme and Alexafluor 647-coupledpeptide substrate (Invitrogen Catalog #5693) is next prepared in advancein a kinase buffer of 50 mM Hepes pH 7.5, 10 mM MgCl2, and 1 mM EGTA.For this solution, the final concentration of the appropriate kinase andpeptide is typically 1 nM and 100 nM, respectively. 5 μL of this 2-foldmix of kinase and peptide is added as the second step of the procedureto the 384-well assay plate.

To initiate the enzymatic reaction, 2.5 μl of a 4-fold excess ATPsolution in kinase buffer is added to the 384-well assay plate. FinalATP concentration is typically set to the Km for ATP. The reaction isallowed to proceed for 60 minutes. During the kinase reaction, a stopsolution consisting of EDTA and a Europium-containing phosphotyrosineantibody (Invitrogen Catalog 5692) is prepared in TR-FRET dilutionbuffer (Invitrogen Catalog #3574). The stop solution contains an EDTAconcentration of 20 mM and an antibody concentration of 4 nM. After the60 minute reaction, 10 μl of the stop solution is added to all wells.Each well is mixed and incubated for 30 minutes at room temperature.Plates are read on a Perkin Elmer Envision TR-FRET plate reader underLanthaScreen settings. Excitation wavelength is 337 nm and Emissionwavelengths are 620 nm and 665 nm. Data are acquired as the ratio ofemission at 665 nm/emission at 620 nm and plotted as a function ofcompound concentration to ascertain compound potency. Here, a signal isobserved only when a Europium-coupled phophotyrosine antibody binds thephosphorylated peptide.

Example 2 BTK Radiometric Enzyme Assay

BTK activity is measured by product formation based on the incorporationof ³³PO₄ from [33P]ATP into a biotin-tagged substrate peptide (see DinhM., et. al., Activation mechanism and steady state kinetics of Bruton'styrosine kinase. J. Biol. Chem. 282:8768-76. 2007). The peptide Isisolated from unreacted [³³P]ATP using streptavidin-coated beads. Eachwell of a 96-well V bottom plate (Greiner, Monroe, N.C.), contains assaybuffer (8 mM imidazole, pH 7.2, 8 mM glycerol 2-phosphate, 200 uM EGTA,20 mM MgCl2, 1 mM MnCl₂, 0.1 mg/nil bovine serum albumin, and 2 mMdithiothreitol) which was combined to 40 ul with a mixture of substratesdissolved in assay buffer such that the final concentrations were 1 uCiof [³³P]ATP, 100 uM ATP, and peptide substrate(biotin-Aca-AAAEETYGEI-NH2). Initiation of the reaction is by additionof BTK to a final concentration of 10 nM. The reaction is incubated at30° C. for 15 min. The reaction is stopped by transferring 25 ul ofsample to a 96-well 1.2-um hydrophilic polyvinylidene difluoride filterplate (Millipore, Billerica, Mass.) containing 10%streptavidin-Sepharose beads (GE Healthcare) dissolved inphosphate-buffered saline plus 50 mM EDTA. Filter plates are washed with2 M NaCl, then with 2 M NaCl with 1% phosphoric acid, and then with H₂O.Plates were allowed to dry and microscint-20 (PerkinElmer Life Sciences,Boston, Mass.) was added. The [³³P] phosphoproduct is detected by atop-count scintillation counter. The enzyme activity is calculated foreach data point. The corrected number of counts in each well isdetermined by subtracting the background counts from the measuredcounts. This value is then divided by the total number of counts thatwere originally present in the solution (determined by spotting andcounting an equivalent volume of unwashed sample on a filter plate) andmultiplied by the concentration of ATP in solution to give theconcentration of phosphorylated product formed. Selectivity for BTK willbe determined using commercially available kinase cross-screeningservices (DiscoveRx, San Diego, Calif.).

Example 6 Blockade of CD69 Expression in Whole Blood Samples

Activation of the B cell receptor leads to increased BTK activity,calcium mobilization and B cell activation (see Honigberg L. A., et.al., Proc Natl Acad Sci USA. 107:13075-80. 2010). BTK inhibitors havebeen shown to block B cell activation as measured by CD69 expression(see Karp, R et. al., Inhibition of BTK with AVL-292 Translates toProtective Activity in Animal Models of Rheumatoid Arthritis.Inflammation Research Association Meeting, September, 2010). We usedexpression of CD69 following cell activation as a measure of BTKactivity in whole blood. Aliquots of whole blood are pre-incubated withserial dilutions of test compound for 30 minutes followed by activationwith anti-IgM (goat Fab′2, 50 ug/ml). Samples are incubated overnight at37 C and then stained with PE labeled anti-CD20 and APC labeledanti-CD69 (BD Pharmingen) for 30 minutes according to the manufacturer'sdirections. Whole blood is then lysed and cells gated on CD20 expressionare quantified for CD 69 expression by FACS. The percent inhibition iscalculated based on a DMSO control for no inhibition and plotted as afunction of test compound concentration from which an IC₅₀ value iscalculated.

Example 7 Inhibition of Mouse Collagen-Induced Arthritis

Inhibition of murine collagen-induced arthritis (mCIA) is a standardanimal disease model for rheumatoid arthritis. Previous studies havedemonstrated that inhibition of BTK is efficacious in blocking mCIA (seeHonigberg L. A., et. al., Proc Natl Acad Sci USA. 107:13075-80. 2010).Starting on day 0 DBA/1 mice are injected with an emulsion of Type IIcollagen in Complete Freund's Adjuvant. Mice are boosted 21 days laterto synchronize development of disease. After development of milddisease, animals are enrolled in the study and randomized. Dosing isoral, Q.D. typically for 11 days with test compound or dexamethasone(0.2 mg/kg) as control. One group receives vehicle alone. Clinicalscoring (0-4) is based on the extent of swelling and severity ofarthritis. Scores for all four paws are added for maximum score of 16.Anti-collagen antibodies and total Ig are measured for each animal byElisa at the end of the study (Bolder BioPath, Boulder, Colo.).

Example 8 Recovery of Kinase Activity Upon Dialysis

Standard experimental methods to establish reversibility are known inthe art. Protein dialysis is one such method. A solution containing aprotein kinase that is inhibited by a compound of Formula I may besubjected to extensive dialysis to establish if the kinase inhibitor isreversible. Partial or complete recovery of protein kinase activity overtime during dialysis is indicative of reversibility.

Method:

A compound of Formula I described herein (1 uM) is added to a solutionof protein kinase (50 nM, pre-activated if necessary) in a buffercontaining 20 mM Hepes [pH 8.0], 10 mM MgCl2, 2.5 mMtris(2-carboxyethyl)phosphine (TCEP), 0.25 mg/mL BSA, and 100 uM ATP.After 60 min at it, the reactions is transferred to a dialysis cassette(0.1-0.5 ml. Slide-A-Lyzer, MWCO 10 kDa, Pierce) and dialyzed against 2L of buffer (20 mM Hepes [pH 8.0], 10 mM MgCl2, 1 mM DTT) at 4° C. Thedialysis buffer is exchanged after 2 h, and then is exchanged every 24 huntil the end of the experiment. Aliquots are removed from the dialysiscassettes every 24 h, flash frozen in liquid nitrogen, and subsequentlyanalyzed for protein kinase activity in triplicate. Kinase activity foreach sample is normalized to the DMSO control for that time point andexpressed as the mean±SD.

Results: Kinase activity recovers from inhibition by reversible kinaseinhibitors upon dialysis. Upon extensive dialysis at 4° C. or at roomtemperature, kinase activity partially or completely recovers in atime-dependent manner from inhibition by an excess (20 equiv, 1.0 uM) ofreversible kinase inhibitor.

Example 9 Mass Spectral Analysis

A protein kinase that is inhibited by compound of Formula I may besubjected to mass spectral analysis to assess the formation ofpermanent, irreversible covalent adducts. Suitable analytical methods toexamine intact full protein or peptide fragments generated upon trypticcleavage of the protein kinase are generally known in the art. Suchmethods identify permanent, irreversible covalent protein adducts byobserving a mass peak that corresponds to the mass of a control sampleplus the mass of an irreversible adduct. Two such methods are describedbelow.

Mass Spectral Analysis of Intact Full Kinase Method:

A protein kinase (5 uM) is incubated with a compound of Formula 1 (25uM, 5 equiv) for 1 h at room temperature in buffer (20 mM Hepes [pH8.0], 100 mM NaCl, 10 mM MgCl2). A control sample is also prepared whichdoes not have a compound of Formula 1. The reaction is stopped by addingan equal volume of 0.4% formic acid, and the samples are analyzed byliquid chromatography (Microtrap C18 Protein column [MichromBioresources], 5% MeCN, 0.2% formic acid, 0.25 mL/min; eluted with 95%MeCN, 0.2% formic acid) and in-line ESC mass spectrometry (LET Premier,Waters). Molecular masses of the protein kinase and any adducts may bedetermined with MassLynx deconvolution software.

Results: High-resolution intact mass spectrometry analysis of a kinasethat is inhibited by a compound of Formula I will reveal a spectrumsimilar to the kinase in the absence of inhibitor (e.g. control sample).There will be no formation of a new peak in the mass spectrumcorresponding to the molecular mass of the kinase plus the molecularmass of the compound of Formula I. On the basis of this experiment nopermanent, irreversible protein adduct will be apparent to one skilledin the art.

Mass Spectral Analysis of Kinase Tryptic Digest Method:

A protein (10-100 pmols) is incubated with a compound of Formula 1(100-1000 pmols, 10 equiv) for 3 hrs prior to tryptic digestion.Iodoacetamide may be used as the alkylating agent after compoundincubation. A control sample is also prepared which does not thecompound of Formula I. For tryptic digests a 1 ul aliquot (3.3 pmols) isdiluted with 10 μl of 0.1% TFA prior to micro C18 Zip Tipping directlyonto the MALDI target using alpha cyano-4-hydroxy cinnamic acid as thedesorption matrix (5 mg/mol in 0.1% TFA:Acetonitrile 50:50) or Sinapinicacid as the desorption matrix (10 mg/mol in 0.1% TFA:Acetonitrile50:50).

Results: High-resolution mass spectrometry analysis of the trypticfragments of a kinase that is inhibited by a compound of Formula I willreveal a spectrum similar to the kinase in the absence of inhibitor(e.g. control sample). There will be no evidence of any modifiedpeptides that are not present in the control sample. On the basis ofthis experiment, no permanent, irreversible protein adducts will beapparent to one skilled in the art. Cellular assays are also optionallyused to assess the inhibiting properties of a compound of Formula Iprovided herein or embodiments thereof. Cellular assays include cellsfrom any appropriate source, including plant and animal cells (such asmammalian cells). The cellular assays are also optionally conducted inhuman cells. Cellular assays of BTK inhibition are well known in theart, and include methods in which an inhibitor is delivered into thecell (e.g. by electroporation, passive diffusion, microinjection and thelike) and an activity endpoint is measured, such as the amount ofphosphorylation of a cellular substrate, the amount of expression of acellular protein, or some other change in the cellular phenotype knownto be affected by the catalytic activity of BTK. For example,phosphorylation of a particular cellular substrate is optionallyassessed using a detection antibody specific or the phosphorylatedcellular substrate followed by western blotting techniques andvisualization using any appropriate means (e.g. fluorescent detection ofa fluorescently labeled antibody).

Measuring the reduction in the BTK catalytic activity in the presence ofan inhibitor disclosed herein relative to the activity in the absence ofthe inhibitor is optionally performed using a variety of methods knownin the art, such as the assays described in the Examples section below.Other methods for assaying BTK activity are known in the art.

The following is a protocol to distinguish whether a compound displays aslow or non-existent dissociation rate from BTK, such as typically wouldoccur if a covalent bond is formed between the compound and the target.The read-out for slow dissociation is the ability of the compound ofinterest to block binding of a high affinity fluorescent tracer moleculeto the kinase active site, as detected using time-resolved fluorescenceresonance energy transfer (TR-FRET). The experiment was conducted in abuffer consisting of 50 mM Hepes pH 7.5, 10 mM MgCl2, 0.01% TritonX-100, and 1 mM EGTA.

The first step of the procedure was incubation of 500 nM BTK (InvitrogenCat. #PV3587) with 1.5 uM of a compound of Formula (IA) for 30 minutesin a volume of 10 uL. The mixture was then diluted 5-fold by addition of40 uL of buffer. A 10 volume of the diluted kinase/compound solution wasthen added to a well of a small volume 384 well plate (such as GreinerCat. #784076). In order to probe for reversibility of thekinase-compound binding interaction, a competition solution containingboth a high affinity fluorescent tracer and an antibody coupled toEuropium was prepared. For BTK, the competition solution contained 1.5uM Tracer 178 (Invitrogen Cat. #PV5593), which is a proprietary highaffinity ligand for BTK coupled to the fluorophore AlexaFluor 647. Thecompetition solution also contained 80 nM of an Anti-polyhistidineantibody coupled to Europium (Invitrogen Cat. #PV5596) which is designedto bind the polyhistidine purification tag in BTK.

After addition of 10 uL of the competition solution to the Greinerplate, the mixture was incubated for one hour or greater to allow timefor dissociation of non-covalent inhibitors and binding of the highaffinity tracer. It was expected that covalent and slow dissociatinginhibitors will block binding of the tracer while rapidly dissociatingnon-covalent inhibitors will not. Binding of the tracer to BTK wasdetected using TR-FRET between the Europium moiety of the Anti-histidineantibody and the AlexaFluor 647 group of Tracer 178. Binding wasevaluated using a Perkin Elmer Envision instrument (Model 2101) equippedwith filters and mirrors compatible with LANCE-type TR-FRET experiments.Data were plotted at percentage of signal obtained in the absence ofcompetitor compound. The background signal was obtained by omission ofBTK from the reaction.

Reversibility of Binding

The following approach was developed to differentiate compounds thatform irreversible bonds with their targets, such as acrylamidecompounds, from compound that bind reversibly. Reactions were preparedwith the protein target at a higher concentration than the compounds ofinterest. Both irreversible and reversible compounds bound the targetand became depleted from solution. The reactions were then treated withperturbations including both denaturation with 5 M guanidinehydrochloride and digestion with trypsin, disrupting proper folding ofthe target. It was found that the perturbation returned reversiblecompounds to solution due to dissociation from the target whileirreversible compounds remained bound to the target. The concentrationof compound in solution was assessed both preceding and followingperturbation using high performance liquid chromatography (HPLC) coupledto tandem mass spectrometry. Using this technique, it was demonstratedthat an acrylamide-containing compound 1 (shown in table below) wasdepleted from solution in both the native and perturbed state, whilereversible compounds 1 and 27 were depleted in the folded state butreturned to solution following perturbation of the target (See tablebelow).
